2 weeks is not long enough for the gas to go bad, but if it was near empty it may have gotten water from condensation in the tank. You'd be surprised how much water can collect, (depending on humidity where you live and temperature differences from day to night) even with the sealed EVAP system clean air must enter the tank as fuel is used, the EVAP prevents fumes from escaping not entering. Try some Sea-Foam, or HEET, although I am not a fan of mechanic-in-a-can stuff, those products help remove water by mixing alcohol with the water and it burns through. Be sure to read label and not get oil treatment. Now...if it was full or near full, maybe a rodent got in intake and built a nest? Happens all the time. Check air filter and intake duct before blower.

Also check for a dirty IAC (Idle Air Control) valve. Might be gummed up enough from normal use to cause it to get stuck from the 2 weeks of inactivity. HTH. -Jim
